Systems and methods for tagging images for placement in portions of a graphical layout based on relative characteristics of depicted faces

ABSTRACT

Systems and methods are described herein for tagging images for placement in a graphical layout based on characteristics of depicted faces. The brightness of each face depicted is determined and, if the brightness of any face is below a threshold level of brightness, the image is tagged with a negative identifier indicating that the image cannot be dimmed. If the brightness of every face exceeds the threshold level of brightness, then the image is tagged with a positive identifier indicating that the image can be dimmed. The resolution of the image is also determined and, if the resolution currently affects any face, the image is tagged with a negative identifier indicating that the image cannot be blurred. If the resolution does not affect any face, and further blurring will not affect any image, then the image is tagged with a positive identifier indicating that the image can be blurred.

BACKGROUND

The present disclosure relates to graphical user interfaces and, moreparticularly, placement of images in portions of a graphical userinterface which is subject to a visual effect.

SUMMARY

Applications of today aim to show comprehensive information in agraphical interface that fits on a single screen. As a result, thelayout of the graphical interface is often divided into severalportions, with each portion dedicated to showing one type ofinformation. The user can interact with each portion of the screen, suchas by scrolling or touch input. Additionally, each portion can besubject to visual effects such as blurring, dimming, and sizeenlargement and/or reduction to fit the screen. The images placed ineach portion of the graphical layout may not be ideal for use with suchvisual effects.

Systems and methods are described herein for tagging images forplacement in a graphical layout and for selecting tagged images topopulate the graphical layout. The overall brightness of an image isdetermined and, if the overall brightness is below a threshold level ofbrightness, the image is tagged with a negative identifier, indicatingthat the image cannot be placed in a portion of the graphical layoutthat will be dimmed. If the overall brightness exceeds the thresholdlevel of brightness, then the image is tagged with a positiveidentifier, indicating that the image can be placed in a portion of thegraphical layout that will be dimmed.

If the overall brightness is above the threshold level of brightness,the image may be partitioned into a plurality of sectors, and theaverage brightness of each sector compared with the average brightnessof each adjacent sector to determine if there is sufficient contrast tomaintain definition between various parts of the image when the image isdimmed. If there is sufficient difference between the brightness of eachsector, then the image is tagged with the positive identifier. If,however, the difference between the brightness of any two adjacentsectors is insufficient, then the image is tagged with the negativeidentifier.

The resolution of the image may be used to determine whether the imagecan be placed in a portion of the graphical layout that will be blurred.The system determines whether any portion of the image is affected bythe overall resolution of the image. If so, then the image is taggedwith a negative identifier, indicating that the image cannot be placedin a portion of the graphical layout that will be blurred. If theoverall resolution does not affect the image, the system determineswhether any portion of the image would be affected by blurring theimage. If so, then the image is tagged with the negative identifier. Ifnot, then the image is tagged with a positive identifier, indicatingthat the image can be placed in a portion of the graphical layout thatwill be blurred.

The system may perform similar analyses based on the effects of dimmingor blurring on faces depicted in the image. The system identifies facesdepicted in the image and determines the relative brightness of eachface. If the relative brightness of any face is below a threshold levelof brightness, then the image is tagged with a negative identifier,indicating that the image cannot be placed in a portion of the graphicallayout that will be dimmed. If the relative brightness of every faceexceeds the threshold level of brightness, then the image is tagged witha positive identifier, indicating that the image can be placed in aportion of the graphical layout that will be dimmed.

The system may determine whether the overall resolution of the imageaffects any of the faces depicted in the image. If the overallresolution affects any face, then the image is tagged with the negativeidentifier. If the overall resolution does not affect any face, then thesystem determines whether any face would be affected by blurring basedon the size of each face. If blurring will affect any face, then theimage is tagged with the negative identifier. If no face will beaffected by blurring, then the image is tagged with a positiveidentifier indicating that the image can be placed in a portion of thegraphical layout that will be blurred.

When populating the graphical layout with images, the system selects animage for placement in a portion of the graphical layout. The systemaccesses a layout that defines a plurality of portions of the graphicallayout and corresponding image parameters for each portion of thegraphical layout. The system selects a first portion of the plurality ofportions and retrieves the corresponding image parameters. If the imageparameters indicate that the selected portion of the graphical layout issubject to a visual effect, the system selects an image having imageparameters, such as the tags described above, indicating that the imagecan be placed in a portion of the graphical interface that will besubject to the particular visual effect. Otherwise, the system selectsan image having image parameters that match the image parameterscorresponding to the selected portion of the graphical interface.

DETAILED DESCRIPTION

FIG. 1 shows an exemplary embodiment of a graphical layout 100 in whichimages are to be placed, in accordance with some embodiments of thedisclosure. Graphical layout 100 includes a large thumbnail image 102 ofa particular episode of the television series “Modern Family.” A playbutton 104 is overlaid on the thumbnail image 102, which the user mayselect to begin watching the episode. Text 106 is placed next tothumbnail image 102 and includes the title of the series, the title ofthe episode, and a description of the episode plot, along with otherinformation related to the episode such as rating, runtime, and airdate. Below thumbnail image 102 is a scrollable area 108 entitled“WatchList,” which contains a number of smaller thumbnails 108 a-108 dof a number of episodes of the series. The border of thumbnail 108 c ishighlighted, indicating that it is the currently selected episode towhich thumbnail image 102 and text 106 correspond. Below WatchList 108is another scrollable area 110 entitled “Cast & Crew,” which containsimages 110 a-110 g of each member of the cast and crew of the series.All of these graphical elements are placed over background area 112,which may also contain an image generally relating to the series, suchas a cast photo, publicity photo, show logo, or other image. An image(not pictured) placed in background area 112 is dimmed or blurred toavoid confusion with the other graphical elements with which the usercan interact. Additionally, any of graphical elements 102, 106, 108, and110 may also be subject to visual effects. As used herein, the term“visual effects” or “image effects” refers to any image manipulationthat alters how an image is displayed to the user. While the methodsdescribed in this disclosure can be used with any suitable visualeffect, this disclosure will discuss only dimming and blurring effects.As described below, images are selected for placement in each portion ofthe graphical layout only if they are suitable for use with relevantvisual effects for each particular portion.

FIG. 2. is a block diagram representing control circuitry and data flowwithin an image processor 200, in accordance with some embodiments ofthe disclosure. Image processor 200 is configured to identifycharacteristics of an image and determine whether the image can besubject to any visual effects. Image processor 200 receives, at controlcircuitry 202, image 204 from image database 206, which may be storedlocally on the same device on which image processor 200 is employed, ormay be stored on a remote server. Control circuitry 202 may be based onone or more microprocessors, microcontrollers, digital signalprocessors, programmable logic devices, field-programmable gate arrays(FPGAs), application-specific integrated circuits (ASICs), etc., and mayinclude a multi-core processor (e.g., dual-core, quad-core, hexa-core,or any suitable number of cores) or supercomputer. In some embodiments,processing circuitry may be distributed across multiple separateprocessors or processing units, for example, multiple of the same typeof processing units (e.g., two Intel Core i7 processors) or multipledifferent processors (e.g., an Intel Core i5 processor and an Intel Corei7 processor).

Control circuitry 202 processes image 204 to determine image parametersof image 204, such as overall brightness and overall resolution. Controlcircuitry 202 compares the overall brightness of the image to athreshold level of brightness. If the overall brightness of image 204 isbelow the threshold level of brightness, control circuitry 202determines that image 204 cannot be placed in a portion of the graphicallayout that will be dimmed and tags image 204 with a negativeidentifier, indicating that the image cannot be dimmed. If the overallbrightness of image 204 meets or exceeds the threshold level ofbrightness, control circuitry 202 determines that image 204 can beplaced in a portion of the graphical layout that will be dimmed, andtags image 204 with a positive identifier, indicating that image 204 canbe dimmed. Alternatively, if the overall brightness of image 204 meetsor exceeds the threshold level of brightness, control circuitry 202partitions image 204 into a plurality of sectors. Control circuitry 202determines the average brightness of each sector and identifies a subsetof sectors having an average brightness that is below the thresholdlevel of brightness. Control circuitry 202 determines whether there issufficient contrast between each sector of the subset of sectors and itsadjacent sectors by comparing the average brightness of each sector ofthe subset of sectors with the average brightness of each adjacentsector. If the difference in brightness is below a second threshold,indicating that there is insufficient contrast between the sectors,control circuitry 202 determines that image 204 cannot be placed in aportion of the graphical layout that will be dimmed and tags image 204with a negative identifier, indicating that image 204 cannot be dimmed.If the difference in brightness meets or exceeds the second threshold,control circuitry 202 determines that image 204 can be placed in aportion of the graphical layout that will be dimmed and tags image 204with a positive identifier, indicating that image 204 can be dimmed.

Control circuitry 202 determines whether the overall resolution of image204 affects any portion of the image. For example, control circuitry 202may use edge detection to identify edges of objects depicted in image204 and analyze color and brightness data for pixels adjacent to eachdetected edge. Control circuitry may determine from the color andbrightness data whether the edge is currently blurred, indicating thatthe resolution of the image currently affects at least one portion ofimage 204. If the overall resolution affects any portion of image 204,control circuitry 202 determines that image 204 cannot be placed in aportion of the graphical layout that will be blurred and tags image 204with a negative identifier, indicating that image 204 cannot be blurred.If the overall resolution does not currently affect any portion of image204, control circuitry 202 determines whether blurring will affect image204. For example, control circuitry 202 determines the smallest distancebetween two opposing edges of each object and compares that distancewith a threshold distance. If the smallest distance between two opposingedges of any object is below the threshold distance, control circuitry202 determines that blurring will affect image 204 and that image 204cannot be placed in a portion of the graphical layout that will beblurred. Control circuitry 202 tags image 204 with a negativeidentifier, indicating that image 204 cannot be blurred. If the smallestdistance between two opposing edges of every object meets or exceeds thethreshold distance, control circuitry 202 determines that blurring willnot affect image 204 and that image 204 can be placed in a portion ofthe graphical layout that will be blurred. Control circuitry 202 tagsimage 204 with a positive identifier, indicating that image 204 can beblurred.

In determining whether image 204 can be dimmed or blurred, controlcircuitry 202 may also analyze the brightness and size of faces depictedin image 204. Control circuitry 202 uses facial recognition to identifyfaces depicted in image 204 and, similar to the brightness analysisdescribed above, control circuitry 202 determines and compares therelative brightness of each depicted face. If the relative brightness ofany face is below a threshold level of brightness, control circuitry 202determines that image 204 cannot be placed in a portion of the graphicallayout that will be dimmed and tags image 204 with a negativeidentifier, indicating that image 204 cannot be dimmed. If the relativebrightness of every face meets or exceeds the threshold level ofbrightness, control circuitry 202 determines that image 204 can beplaced in a portion of the graphical layout that will be dimmed and tagsimage 204 with a positive identifier, indicating that image 204 can bedimmed. Similar to the resolution analysis described above, controlcircuitry 202 determines whether the overall resolution of image 204affects any face depicted in image 204. If the overall resolutionaffects any face, control circuitry 202 determines that image 204 cannotbe placed in a portion of the graphical layout that will be blurred andtags image 204 with a negative identifier, indicating that image 204cannot be blurred. If the overall resolution does not affect any face,control circuitry 202 determines the minimum width of each face andcompares the minimum width of each face to a threshold width todetermine whether blurring will affect any face. If the minimum width ofany face is below the threshold width, control circuitry 202 determinesthat image 204 cannot be placed in a portion of the graphical layoutthat will be blurred and tags image 204 with a negative identifier,indicating that image 204 cannot be blurred. If the minimum width ofeach face meets or exceeds the threshold width, control circuitry 202determines that image 204 can be placed in a portion of the graphicallayout that will be blurred and tags image 204 with a positiveidentifier, indicating that image 204 can be blurred.

After tagging the image with positive and/or negative identifiers,control circuitry 202 incorporates the tags into image parameters ofimage 204 and transmits the image parameters 208 back to image database206 for storage in association with image 204.

Image processor 200 is also configured to select images for placement ina graphical layout in which visual effects are used. Image processor 200receives input 210 using input circuitry 212. Input 210 is, for example,a request from a media device for images to populate a graphical layout.Input 210 may alternatively be a request for single image to be placedin a particular portion of the graphical layout. Input 210 may includeimage parameters of the particular portion of the graphical layout inwhich the image is to be placed. Input 210 may be in the format of anHTTP request, database query, or suitable data access request. Inputcircuitry 212 may be a modem, ethernet connection, WiFi receiver, USBconnection, or any other suitable data connection. Alternatively, ifimage processor 200 is integrated into the media device, input circuitry212 may be a data bus interface or other suitable integrated hardwareconnection, and input 210 may be in the format of a serial datatransmission or other suitable hardware transmission format. Inputcircuitry 212 processes input 210 and transmits a signal 214corresponding to input 210 to control circuitry 202.

In response to receiving the signal 214 from input circuitry 212,control circuitry 202 transmits a query 216 to image database 206 forimages having image parameters that match image parameters included ininput 210. Image database 206 returns at least one image 218 to controlcircuitry 202 that can be placed in the graphical layout. Controlcircuitry 202 transmits 220 image 218 to output circuitry 222. Outputcircuitry 222 may be a modem, ethernet connection, WiFi transmitter, USBconnection, or any other suitable data connection. Alternatively, ifimage processor 200 is integrated into the media device, outputcircuitry 222 may be a data bus interface or other suitable integratedhardware connection, and transmission 220 may be in the format of aserial data transmission or other suitable hardware transmission format.Output circuitry 222 receives transmission 220 and relays 224transmission 220 containing image 218 to a display device for placementin the graphical layout.

In some embodiments, input 210 identifies a particular portion of aparticular layout for which an image is requested, rather than specificimage parameters corresponding to the particular portion of theparticular layout. Control circuitry 202, upon receiving signal 214corresponding to input 210, transmits a request 226 to memory 228 for alayout data corresponding to the identified graphical layout. Memory 228may be any device for storing electronic data such as random-accessmemory, read-only memory, hard drives, optical drives, digital videodisc (DVD) recorders, compact disc (CD) recorders, BLU-RAY disc (BD)recorders, BLU-RAY 3D disc recorders, solid state devices, quantumstorage devices, or any other suitable fixed or removable storagedevices, and/or any combination of the same. In response to request 226,memory 228 transmits the requested layout data 230 to control circuitry202. Control circuitry 202 extracts from layout data 230 the imageparameters of the identified portion of the particular graphical layoutand queries image database 206 for an image matching the imageparameters. If the identified portion of the graphical layout will besubject to an image effect, control circuitry selects an image fromimage database 206 having image parameters that indicate, based on thetags described above, that the image can be placed in a portion of thegraphical layout that will be subject to the image effect. If theidentified portion will not be subject to an image effect, controlcircuitry 202 selects an image from image database 206 having matchingimage parameters to those extracted from the layout data.

Control circuitry 202 may determine from the layout data whether anoverlay will be placed over the identified portion of the graphicallayout. If so, control circuitry 202 determines the position of theoverlay relative to the position of the identified portion of thegraphical layout. Control circuitry 202 then retrieves a plurality ofimages from image database 206 which can be placed in the identifiedportion of the graphical layout (i.e., images having image parametersthat match the image parameters in the layout data for the particularportion of the graphical layout and having tags indicating they can beplaced in portions of the layout which will be subject to any visualeffects associated with the particular portion) and identifies, for eachimage, a portion of the image that will be covered by the overlay.Control circuitry 202 then determines for each image whether the overlaywill significantly reduce visibility of the portion of the image whichwill be covered by the overlay, and selects an image for which theoverlay will not significantly reduce visibility of the portion of theimage.

FIG. 3 is a flowchart representing an illustrative process 300 fortagging an image, based on the overall brightness of the image, forplacement in a portion of the graphical interface which will be dimmed,in accordance with some embodiments of the disclosure. Process 300 maybe implemented on control circuitry 202. In addition, one or moreactions of process 300 may be incorporated into or combined with one ormore actions of any other process or embodiment described herein.

At 302, control circuitry 202 determines the overall brightness of theimage. For example, control circuitry analyzes color data for each pixelof the image and identifies, based on the color data, a brightness foreach pixel. Control circuitry 202 then averages the brightness of eachpixel to obtain an average brightness for the entire image.

At 304, control circuitry 202 determines whether the overall brightnessof the image is below a threshold level of brightness. If the overallbrightness is below the threshold level of brightness, then, at 306,control circuitry 202 determines that the image cannot be placed in aportion of the graphical layout which will be dimmed. At 308, controlcircuitry 202 tags the image with a negative identifier, indicating thatthe image cannot be dimmed.

If the overall brightness of the image meets exceeds the threshold levelof brightness, then, at 310, control circuitry 202 determines that theimage can be placed in a portion of the graphical layout that will bedimmed. At 312, control circuitry 202 tags the image with a positiveidentifier, indicating that the image can be dimmed.

The actions and descriptions of FIG. 3 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 3 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.

FIG. 4 is a flowchart representing another illustrative process fortagging an image, based on the overall brightness of the image, forplacement in a portion of the graphical interface which will be dimmed,in accordance with some embodiments of the disclosure. Process 400 maybe implemented on control circuitry 202. In addition, one or moreactions of process 400 may be incorporated into or combined with one ormore actions of any other process or embodiment described herein.

While an image may have an overall brightness that exceeds the thresholdlevel of brightness, the image may have several darker areas which mayno longer be distinguishable from one another if the image is furtherdimmed. At 402, control circuitry 202 compares the overall brightness ofthe image to the threshold level of brightness. If the overallbrightness meets or exceeds the threshold level of brightness, then, at404, control circuitry 202 partitions the image into a plurality ofsectors. At 406, control circuitry determines the average brightness ofeach sector of the image. At 408, control circuitry 202 identifies asubset of sectors having an average brightness below the threshold levelof brightness. At 410, control circuitry 202 compares the averagebrightness of each sector of the subset of sectors with the averagebrightness of each adjacent sector.

At 412, control circuitry 202 determines, based on the comparison,whether the difference in brightness between any sector and one of itsadjacent sectors is lower than a threshold difference in brightness. Ifso, then, at 414, control circuitry 202 determines that the image cannotbe placed in a portion of the graphical layout that will be dimmed and,at 416, control circuitry 202 tags the image with a negative identifier,indicating that the image cannot be dimmed. If the difference inbrightness between each sector and all adjacent sectors meets or exceedsthe threshold difference in brightness, then, at 418, control circuitry202 determines that the image can be placed in a portion of thegraphical layout that will be dimmed and, at 420, control circuitry 202tags the image with a positive identifier, indicating that the image canbe dimmed.

The actions and descriptions of FIG. 4 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 4 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.

FIG. 5 is a flowchart representing an illustrative process 500 fortagging an image, based on the overall resolution of the image, forplacement in a portion of the graphical interface which will be blurred,in accordance with some embodiments of the disclosure. Process 500 maybe implemented on control circuitry 202. In addition, one or moreactions of process 500 may be incorporated into or combined with one ormore actions of any other process or embodiment described herein.

At 502, control circuitry 202 determines the overall resolution of theimage. Control circuitry 202 may access metadata of the image whichindicates the resolution of the image. Alternatively, control circuitry202 may determine the dimensions of the image in pixels. At 504, controlcircuitry 202 determines whether the overall resolution of the imageaffects any portion of the image. For example, control circuitry 202identifies a plurality of objects depicted in the image using edgedetection. Control circuitry 202 then determines, for each object,whether the edge of the object is blurred based on color and brightnessdata corresponding to each pixel of the image that is adjacent to thedetected edge of the object. If the overall resolution of the imageaffects any portion of the image, then, at 506, control circuitry 202determines that the image cannot be placed in a portion of the graphicallayout that will be blurred and, at 508, control circuitry 202 tags theimage with a negative identifier, indicating that the image cannot beblurred.

If the overall resolution does not affect any portion of the image,then, at 510, control circuitry 202 determines whether blurring willaffect any portion of the image. If so, then processing returns to step506. If not, then, at 512, control circuitry 202 determines that theimage can be placed in a portion of the graphical interface that will beblurred and, at 514, control circuitry 202 tags the image with apositive identifier, indicating that the image can be blurred.

The actions and descriptions of the FIG. 5 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 5 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.

FIG. 6 is a flowchart representing another illustrative process 600 fortagging an image, based on the overall resolution of the image, forplacement in a portion of the graphical interface which will be blurred,in accordance with some embodiments of the disclosure. Process 600 maybe implemented on control circuitry 202. In addition, one or moreactions of process 600 may be incorporated into or combined with one ormore actions of any other process or embodiment described herein.

At 602, control circuitry 202 determines, for each object depicted inthe image, the minimum distance between opposing sides of the edge ofthe object. For example, an object having an irregular shape may havesections that are wide and sections that are narrow. While the overallresolution of the image preserves the narrowest portion of the object,further blurring may obscure or remove the narrowest portion of theobject from view. At 604, control circuitry 202 determines whether theminimum distance between opposing sides of the edge of the object isbelow a threshold distance. If so, then, at 606, control circuitry 202determines that blurring will affect the image. In response, at 608,control circuitry 202 determines that the image cannot be placed in aportion of the graphical interface that will be blurred and, at 610,tags the image with a negative identifier, indicating that the imagecannot be blurred.

If the minimum distance between opposing sides of the edge of the objectmeets or exceeds the threshold distance, then, at 612, control circuitry202 determines that blurring will not affect the image. In response, at614, control circuitry 202 determines that the image can be placed in aportion of the image that will be blurred and, at 614, control circuitry202 tags the image with a positive identifier, indicating that the imagecan be blurred.

The actions and descriptions of FIG. 6 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 6 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.

FIG. 7 is a flowchart representing an illustrative process 700 fortagging an image, based on the relative brightness of faces depicted inthe image, for placement in a portion of the graphical layout which willbe dimmed in accordance with some embodiments of the disclosure. Process700 may be implemented on control circuitry 202. In addition, one ormore actions of process 700 may be incorporated into or combined withone or more actions of any other process or embodiment described herein.

At 702, control circuitry 202 identifies a plurality of faces depictedin the image using facial recognition. At 704, control circuitry 202determines the relative brightness of each face. For example, controlcircuitry 202 analyses color and brightness information of the pixelsthat comprise each face to determine an average brightness for eachface. Control circuitry 202 then determines the face with the lowestbrightness and the face with the highest brightness and scales alldetected faces between the lowest and highest brightnesses.

At 706, control circuitry 202 determines whether the relative brightnessof a face is below a threshold level of brightness. If so, then, at 708,control circuitry 708 determines that the image cannot be placed in aportion of the graphical layout that will be dimmed and, at 710, controlcircuitry 202 tags the image with a negative identifier, indicating thatthe image cannot be dimmed. If the relative brightness of each facemeets or exceeds the threshold level of brightness, then, at 712,control circuitry 202 determines that the image can be placed in aportion of the graphical layout that will be dimmed and, at 714, controlcircuitry 202 tags the image with a positive identifier, indicating thatthe image can be dimmed.

The actions and descriptions of FIG. 7 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 7 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.

FIG. 8 is a flowchart representing an illustrative process 800 fortagging an image, based on the size of faces depicted in the image, forplacement in a portion of the graphical interface which will be blurredin accordance with some embodiments of the disclosure. Process 800 maybe implemented on control circuitry 202. In addition, one or moreactions of process 800 may be incorporated into or combined with one ormore actions of any other process or embodiment described herein.

At 802, control circuitry 202 determines the overall resolution of theimage. This may be accomplished using methods described above inconnection with FIG. 5. At 804, control circuitry 202 determines whetherthe overall resolution of the image affects any face. This may also beaccomplished used methods described above in connection with FIG. 5. Ifthe overall resolution of the image affects any face, then, at 806,control circuitry 202 determines that the image cannot be placed in aportion of the graphical layout that will be blurred and, at 808,control circuitry 202 tags the image with a negative identifier,indicating that the image cannot be blurred.

If the overall resolution does not affect any face, then, at 810,control circuitry 202 determines the minimum width of each face and, at812, control circuitry 202 determines whether the minimum width of eachface exceeds a threshold width. If the minimum width of any face doesnot exceed the threshold width, then processing returns to step 806. Ifthe minimum width of every face exceeds the threshold width, then, at814, control circuitry 202 determines that the image can be placed in aportion of the graphical layout that will be blurred and, at 816,control circuitry 202 tags the image with a positive identifier,indicating that the image can be blurred.

The actions and descriptions of FIG. 8 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 8 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.

FIG. 9 is a flowchart representing a process 900 for selecting an imagefrom a database for placement in a portion of the graphical interface inaccordance with some embodiments of the disclosure. Process 900 may beimplemented on control circuitry 202. In addition, one or more actionsof process 900 may be incorporated into or combined with one or moreactions of any other process or embodiment described herein.

At 902, control circuitry 202 accesses, from memory 228, a layout thatidentifies a plurality of portions of the graphical layout andcorresponding image parameters for each portion of the graphical layout.At 904, control circuitry 202 selects a portion of the graphical layout.The selected portion may correspond to a particular portion indicatedin, for example, input 210. At 906, control circuitry 202 retrievescorresponding image parameters of the selected portion from the layout.At 908, control circuitry 202 access a database of images (e.g., imagedatabase 206), each image having corresponding image parameters. At 910,control circuitry 202 determines whether the selected portion of thegraphical layout will be subject to an image effect. For example,control circuitry 202 may extract, from the layout, image effectindicators from the image parameters corresponding to the selectedportion of the graphical layout.

If the selected portion of the graphical layout will be subject to animage effect, then, at 912, control circuitry 202 selects, from thedatabase, for placement in the selected portion, an image having imageparameters (e.g., a tag applied according to the methods describedabove) indicating that the image can be placed in a portion of thegraphical layout that will be subject to the image effect. If theselected portion of the graphical layout will not be subject to an imageeffect, then, at 914, control circuitry 202 selects, from the database,for placement in the selected portion, an image having image parametersthat match the image parameters corresponding to the selected portion ofthe graphical layout.

The actions and descriptions of FIG. 9 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 9 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.

FIG. 10 is a flowchart representing another illustrative process 1000for selecting an image from a database for placement in a portion of thegraphical interface in accordance with some embodiments of thedisclosure. Process 1000 may be implemented on control circuitry 202. Inaddition, one or more actions of process 1000 may be incorporated intoor combined with one or more actions of any other process or embodimentdescribed herein.

At 1002, control circuitry 202 determines whether an overlay will bedisplayed over the selected portion of the graphical layout. Forexample, control circuitry 202 may extract from the layout position anddimension parameters for each portion of the graphical layout anddetermine, based on the position and dimension parameters, whether anyportion will overlap with another portion. At 1004, control circuitry202 determines a position of the overlay relative to the position of theselected portion. At 1006, control circuitry 202 retrieves from adatabase of images (e.g., image database 206) a plurality of images thatcan be placed in the selected portion of the graphical layout.

At 1008, control circuitry 202 initializes a counter variable N and setsits value to 0. At 1010, control circuitry 202 identifies, in the N^(th)image, a portion of the image that will be covered by the overlay. Forexample, using the position and dimension parameters, control circuitry202 determines a specific area or sector of the image that will becovered by the overlay. At 1012, control circuitry 202 determineswhether the overlay will significantly reduce visibility of the portionof the image. For example, control circuitry 202 determines, based onthe dimension parameters of the overlay, how much of the image will becovered by the overlay. Control circuitry 202 then identifies objectsdepicted in the portion of the image and whether such objects occupy alarger portion of the image than the portion that will be covered by theoverlay. If the overlay will completely cover a small object, thencontrol circuitry 202 may determine that the overlay will significantlyreduce visibility of the portion of the image. If, however, the overlaywill partially cover a larger object, control circuitry 202 maydetermine that the overlay will not significantly reduce visibility ofthe portion of the image.

If the overlay will not significantly reduce the visibility of theportion of the N^(th) image, then, at 1014, control circuitry 202selects the N^(th) image for placement in the selected portion of thegraphical layout. If, however, the overlay will significantly reducevisibility of the portion of the N^(th) image, then, at 1016, controlcircuitry 202 determines whether there are additional images to analyzeand, if so, at 1018, control circuitry 202 increments the value ofcounter variable N by one and processing returns to step 1010.

The actions and descriptions of FIG. 10 may be used with any otherembodiment of this disclosure. In addition, the actions and descriptionsdescribed in relation to FIG. 10 may be done in suitable alternativeorders or in parallel to further the purposes of this disclosure.
